How then, do we move backwards? How does a society, with most of the people having no clue of future events, move from being dependent on a vast and intertwined network of goods and services produced by the indigenous people of whereever, to a local resource and renewable energy based society, and do so in the timeframe available (20-30 years using the most liberal extimates, 10-20 with resonable estimates, 5-10 with worst case scenarios), all the while prices on everything increasing, world politics getting more militaristic, governments continuously reducing civil liberties, shortages of goods on the market and weather patterns resembling bad Hollywood movies?

I've been working on a Stoddard cycle engine for a year or so now, thinking I had invented an improvement to the Stirling. (I just found the patent) As such, I have read an awful lot of stuff on the subject, so I think getting hold of one of those old engines would be really neat.
They are very simply built and quite robust I expect. Just looking briefly, I don't think many on that list are true stirling, but that doesn't matter does it.
Commercially now, there are two manufacturers, one in N.Z., and one in America. As for the old ones, you're looking at probably under 10% efficiency. I say this because Sunpower, a very high tech manufacturer of free piston stirlings gets only 30% efficiency out of their engines. Sunpower has been working on linear alternator free piston stirlings for 30+ years.
